1. Lecture 1 Flashcards
What is an animal?
Multicellular eukaryotic organisms that have well-defined shape and usually limited growth, can move voluntarily, actively acquire food and digest it internally, and have sensory systems that allow them to respond to stimulus.
Reasons to study behavior
Conserve and protect endangered species
Understand actions of economically important predators, pests, and parasites
Understand domesticated animals to better serve us
Improve welfare of animals particularly those in captivity
Three approaches to studying behavior
Conceptual, Theoretical, and Empirical using the scientific method
Aristotle
Wrote about natural history of animals
First extensive use of observational behavior
Charles Darwin
Made countless observations of animals in their natural setting while sailing onboard the Beagle.
Formulated theory of natural selection
Gregor Mendel
Established key principles of the laws of inheritance of biological characteristics through experimenting with garden peas
Classical Ethology
Europe
Evolution, function, and mechanisms of behavior
Looked at species differences
Studied animals in their natural habitat
Looked at innate behavior
Comparative Psychology
USA
Mechanisms and development of behavior
Laws of behavior
Studied animals in lab setting
Focused on learned behavior
John Watson
Principal founder of school of behaviorism.
Animal behavior consists of an animals responses, reaction, or adjustments to stimuli or complexes of stimuli
Edward Thorndike
Puzzle box - cat in a box discovering how to get out
Responses that are rewarded tend to be repeated
The process of learning must be the same in all species
B.F. Skinner
Operant cages (Rat in a box)
Concentrated on describing stimulus and response it elicits: control of behavior was basically a matter of reinforcement
Konrad Lorenz
Pioneered studies of genetically programmed behavior
Investigated importance of specific types of stimulation for young animals during critical periods of early development
Imprinting is genetically programmed
Releasing stimuli: Specific types of stimulation for young animals during critical periods of early development
Karl von Frisch
Conducted research on animal sensory process and made important contributions to the study of bee communication
Niko Tinbergen
Developed the scheme with which modern ethology is founded
Four areas of inquiry: causation, development, evolution, and function of behavior (“the four questions”)
